A 16-sided polygon is called a hexadecagon or sometimes a hexakaidecagon. The term ‘hexadecagon’ is derived from the Greek words ‘hexa’ meaning six and ‘deca’ meaning ten, combined with ‘gon’ meaning angle or corner. This naming convention follows the standard way of naming polygons based on the number of their sides.
In geometry, polygons are classified based on the number of sides they have. A hexadecagon, with its 16 sides, falls under the category of complex polygons, especially when it comes to constructing or drawing one accurately. Each internal angle of a regular hexadecagon (where all sides and angles are equal) measures 157.5 degrees, and the sum of all internal angles is 2520 degrees.
Understanding the properties and names of polygons like the hexadecagon is fundamental in geometry, as it helps in the study of shapes, their properties, and their applications in various fields such as architecture, engineering, and design.
